REFERENCE TO RELATED APPLICATIONS

[0001] This invention relates to improvements in fencing systems andother outdoor structures, and more particularly relates to improvedapparatus and methods of construction and use that allows the functionand uses of the structure to be expanded and the construction, functionand appearance of the structure to be selectively adjusted or changed tomeet varying conditions of display and use. The invention isparticularly suitable for use with fencing systems and other outdoorstructures constructed from plastic materials such as PVC.

BACKGROUND INFORMATION

[0002] Fencing is commonly used in public and private locations toprovide security by barring entry to the enclosed locations to provideprivacy, or to improve the aesthetic appearance of the area. Mostfencing has a fixed structural design. The fence remains permanently inessentially the same condition of appearance and use after it isinstalled in the desired location. Expensive maintenance is oftenrequired to preserve the original condition of the fence. Anysubstantial change in the function, use or appearance of the fenceusually requires laborious activity such as reconstruction or painting.These prior fence constructions are not adaptable for performingadditional functions and are not changeable or adjustable to provide thefence with a new or different use or appearance.

[0003] The arrangement and appearance of the fencing are particularlystatic or difficult to change when the fence is constructed of plasticmaterials such as polyvinyl chloride (PVC) and the like, a type offencing that is becoming increasingly more prevalent. Plastic fencingtypically must have a selected design and be manufactured, such as bymolding or extrusion off-site at a factory. Only minor variations in thestructure of the PVC or other plastic fencing can be accomplished at thesite where the fence is to be installed to vary the use or appearance ofthe structure or adapt the structure to perform additional functions.Major changes in construction or design would require costly changes tothe manufacturing process to create the different parts of a fence atthe factory. The costs of storing or inventorying the number ofdifferent component parts having different functions or appearances isalso very substantial.

[0004] The color and appearance of PVC or other plastic fencing oroutdoor structures such as railing and decking are also difficult tochange. Plastic materials are susceptible to degradation in sunlight dueto the effect of ultraviolet rays. A plastic composition includingtitanium dioxide, a well known white pigment, provides a measure ofprotection from this potential degradation of the material when exposedto an outside environment. As a result, plastic fencing is usually awhite or light color when treated with titanium dioxide or the like tominimize the possibility of degradation that may occur.

[0005] Some of these same disadvantages also arise with other outdoorstructures, such as an outside rail or a deck that is constantly exposedto the elements. For example, it is difficult to change the function orappearance of an outdoor rail or deck component once it is installed inplace, particularly if the structure is constructed from a plasticmaterial such as PVC. Substantial costs would also be involved inattempting to manufacture and inventory the different components neededto selectively change the function or appearance of the structure.

[0006] Many current designs for fencing, railings and decks are alsodifficult to use with electrical wires, or fluid or air lines, andcannot readily accommodate the addition of useful attachments such ashangers for tools or utensils, work or support surfaces or the like.Such additional features and functions are particularly difficult to addto a fence or other structure manufactured at an off-site factory from aplastic material such as PVC. Many prior structures would have to besubstantially reconstructed or replaced to be useful with electricalwires, fluid lines or various attachments.

BRIEF SUMMARY

[0007] This invention provides improved apparatus and methods ofconstruction and use for fencing and other outdoor structures that allowthe structure to be readily adapted to perform additional functions orchanged to vary the use or appearance of the structure. In utilizingthis invention the fencing, as an example, would not merely perform astatic function such as dividing areas, providing privacy or barringentry to an area. With this invention the structure is readily adaptedfor additional features or functions and can be changed or adjustedeasily for a different appearance or use. A fence incorporating thisinvention can be adapted or adjusted selectively to adapt to changes inlighting, such as changes in sunlight; to vary viewing or privacyconditions; to enhance security; to regulate ventilation or airflow; tocollect solar energy; to adapt the structure to accommodate changes inseasons or holidays; to attach implements, tools or decorative items, toprovide distribution channels for electrical wiring or air or waterconduits, and to permit other desired adjustments or changes. Theadjustable components of the fencing can be releasably locked into theselected position after the desired adjustment is made. In one aspect ofthe invention the improved structure provides a readily accessiblecompartment or pathway for receiving devices such as wiring or fluidlines, for storing items such as wires and hoses or for retaining itemssuch as floral or garden arrangements, bird seed feeders or the like.The improved structure further includes an attachment feature thatallows other components such as hangers or support structures to beeasily attached.

[0008] The invention further provides apparatus and methods to readilychange the appearance of the structure to suit particular needs ordesires. The structure such as a fence, railing or deck component can bevaried after installation by changing the color, texture or otherappearance of the structure in a low-cost and efficient manner. Byutilizing this invention with PVC or other plastic fencing, railing ordecks can be changed from the traditional light or white colors to othershades of colors including darker colors and/or different textures.Changes in the appearance of the structure can be done to accommodatethe changes in seasons or holidays, to match or coordinate with thecolors of other structures such as adjacent houses, to improvevisibility or safety, or to suit other needs or desires of the user.

[0009] In general the present invention relates to a method andapparatus for an outdoor structure that is capable of adjustment to varythe conditions of use. When used as a fence, this system includes fencerails for supporting a portion of the fence and movable fence members.Supporting structure support the fence members on the rails and allowsthem to be selectively adjusted to a plurality of positions andreleasably locked into these selected positions. The invention providesa method and apparatus for altering or modifying the appearance of anoutdoor structure such as a fence, railing or deck member. Each of theoutdoor members include a structure having a selected face provided witha gripping element. A separate panel having a different selectedappearance or color is engaged with the gripping element to modify theface of the outdoor structure. The member in accordance with inventionfurther can define a compartment or pathway which is readily accessibleand closable for receiving and storing a variety of objects.

DETAILED DESCRIPTION OF THE DRAWINGS AND THE PRESENTLY PREFERREDEMBODIMENTS

[0052]FIG. 1 illustrates a front elevational view of a portion of thefence 10 constructed in accordance with the present invention. The fence10 includes vertical fence posts 12 and 14 and top and bottom horizontalfence rails 16 and 18. End caps 13 are placed on the upper ends of thesupporting fence posts 12 and 14. In the preferred embodiments thesecomponents of the fence 10 are hollow and can be constricted fromplastic materials such as polyvinyl chloride (PVC). The plastic memberscan be injection or blow molded, or extruded, and the like.

[0053] The Fence 10 includes a series of fence members or pickets 20positioned between the top and bottom fence rails 16 and 18. Theillustrated fence members 20 are vertical but the members can bearranged horizontally, diagonally or in other positions that may bedesired. These fence members or pickets 20 can be selectively andreadily adjusted to change the use, function, or appearance of the fence10.

[0054]FIGS. 1 and 2 illustrate the fence members 20 being positioned inseveral different orientations for illustrative purposes. As seen inFIG. 1, each fence member 20 is movably supported on the upper fencerail 16 by an upper support structure 22 and supported on another rail18 by an additional support structure 24. The illustrated fence includestwo rails but it will be appreciated that additional rails can beprovided on the fence.

[0055]FIGS. 3 and 4 illustrate the detailed construction of oneembodiment for the upper support structure 22 for each of the fencemembers 20. As seen in FIG. 4, this upper support structure 22 includesa threaded fastener 26 which is secured by a friction fit, adhesive orother suitable means to an aperture provided in the top of the fencemember 20. One end portion of the fastener 26 can take the form of ahex-head 26A and the other end of the fastener includes a threadedportion 26B. The fastener 26 can be provided with an aperture 28 whichprovides a channel through which components such as electrical wiring,fluid or air lines or the like can be extended to communicate betweenthe inside hollow portions of the rail 16 and the fence member 20.

[0056] The fence rail 16 is provided with an aperture which receives thethreaded end 26B of the fastening member 26, as illustrated in FIG. 4.The upper support structure 22 also includes a threaded locking nut 27designed to engage with the threaded portion 26B of the fastener 26. Thelocking nut 27 is preferably hex-shaped so that it can be rotatedmanually or by using a conventional wrench or other tool to raise orlower the locking nut 27 on the fastener 26. Rotation of the member 20is permitted when the locking nut 27 is spaced from the upper rail 16.The nut 27 may be used to lift the member 20 for rotation. Thisarrangement for the upper support structure 22 permits the fence member20 to be rotated about a vertical axis by rotation of the fastener 26Bwithin the aperture in the rail 16 and the resulting rotation of thefence member 20 with respect to the rail 16. The locking member, asshown in FIG. 4, is placed between the fence member 20 and the end rail16 on the fastener 26.

[0057] Once the fence member 20 is positioned in the desired locationthrough the rotation about the vertical axis, the locking nut 27 can beadvanced on the threaded portion 26B of the fastener 26 against the rail16 to releasably lock the fence member 20 in the selected position. Ifit is later desired to move the fence member 20 into a differentselective position, the locking nut 27 can be rotated to release thefence member 20 and permit the member to once again rotate with respectto the rail 16. In this manner, the fence member 20 can be moved into avariety of orientations between the upper fence rail 16 and the lowerfence rail 18 to adapt the fence for performing additional functions orto give the fence a different appearance.

[0058]FIGS. 5 through 9 illustrate a second embodiment for the uppersupport structure associated with each of the fence members 20. In thisembodiment, the top end of each hollow fence member 20 is provided withan end cap 28. This end cap 28 is held in place by a friction fit,adhesive or other suitable means, and includes a tab 30 which can beused to move the fence member 20 for rotation. The tab 30 is preferablypositioned on the inside face of the fence member 20 to enhance thesecurity provided by the fence. The end cap 28 also carries a plungerhousing 32 which receives a spring loaded plunger 34 having acompression coil spring 39, as shown in FIGS. 8 and 9. A pin 29 withinthe housing 32 retains the spring 39 in place. A base portion 36 has acircular element 38 and a shoulder 36A. The plunger 34 fits within thehousing 32. The circular element 38 is rotatably positioned in anaperture in the lower part of the rail 16 and allows the member 20 to berotated with respect to the rail. Flange 36B on the plunger base 36retains the base 36 in place within the plunger housing 32. The shoulder36B engages the top rail 16 so that the spring 39 urges the member 20downwardly and releasably secures the member in a selected position bycooperating with the lower support structure 24 of the fence inaccordance with this invention. As shown in FIG. 9, an aperture 35 canbe provided in the center of the plunger assembly 34 to define a passagefor wires or fluid lines or the like and thereby permit communicationbetween the fence member 20 and the hollow rail 16. The fence member 20can be formed to be hollow or have an opening to receive the wires,fluid lines or other objects.

[0059]FIGS. 10 through 12 illustrate a third embodiment for the uppersupport structure usable in the fence assembly in accordance with thisinvention. In this embodiment, the upper end of the fence member 20 isprovided with a pivot pin 40 and the adjacent lower portion of the upperfence rail 16 is provided with a collapsible tensioning member 42.Preferably, the width of the tensioning member 42 is selected to be atleast substantially the same as the width of the fencing member 20, asshown in FIG. 10. Alternatively, the tensioning member 42 can extendalong the length of the rail 16 and can be attached to or formed on therail. In this manner, the open space between the fence member 20 and therail 16 is closed by the tensioning member 42. The member 42 will thusimprove the privacy or protection provided by the fence 10. The lowerportion of the tensioning member 42 is provided with an aperture 44 toreceive the pin 40, as shown in FIGS. 11 and 12.

[0060] In accordance with this embodiment of the invention, thetensioning member 42 is constructed from a pliable material such asflexible plastic or elastomeric material. With this construction, thetensioning member 42 will flex and allow the fence member 20 to be movedagainst the biasing force of the tensioning member 42. When a movingforce is applied to the fence member 20, the collapsible tensioningmember 42 allows the member 20 to be rotated into the desired position.The member 42 then applies a tensioning biasing force to the member 20to releasably secure the fence member 20 in the selected position.

[0061]FIGS. 13 through 15 illustrate a design for a second supportstructure 24 for each of the fence members 20 in accordance with thepresent invention. One component of the illustrated lower supportstructure comprises an insert 50 designed to be fixed by suitable meansto the adjacent end of each fence member 20. The insert 50, as shown inFIG. 13, includes a pivot pin 52 positioned in the central portion ofthe insert. This pin 52 preferably has a tapered end 54 to facilitatethe guiding of the pin 52 into place. The insert 50 further includesdetent members 56 which are spaced about the periphery of the pin 52 asshown in FIGS. 13 and 14. These detent members 56 have a selected shapeand are positioned around the pin 52 in a uniform pattern. In theillustrated embodiment shown in FIG. 14, the detent members 56 comprisea plurality of radial extensions spaced uniformly 60 degrees apartaround the periphery of the pin 52. The pin 52 can also include anaperture 55 defining a passage for wire or fluid or air lines or thelike which can be extended between for communication between theinterior of the fence member 20 and the interior of the lower rail 18.

[0062]FIG. 15 illustrates alternative configurations for the lower rail18 of the fence 10 in accordance with the present invention. The upperportion of the rail 18 is provided with an indexing and locking aperture58A configured to receive the pin 52 and engage with detent members 56on the lower support structure 50. Several alternative locking apertures58B-E are also illustrated in FIG. 15. Each of these apertures 58A-Ehave a periphery with a selected pattern of detent surfaces 60A-Edesigned to cooperate with complementary detent members 56 on the lowersupport structure 50. The detents 56 can be arranged to be a selectednumber of degrees apart around the periphery of the pin 54 to becompatible with the corresponding shape of the aperture 58A-E and thedetent surfaces 60A-E. Locking aperture 58A is compatible with thedetent members 56 in the illustrated embodiment. The particularconfiguration for the detents 56 and the corresponding peripheralapertures 60 in the openings 58A-E can be chosen to provide a selectednumber of fixed positions for the adjustable fence member 20. Theillustrated detents 56 and the apertures 60A are positioned 60 degreesapart. If the lower support structure is to be retrofitted to anexisting fence the apertures 58A-E can be provided on a separate memberthat can be fastened to the fence rail.

[0063] The lower support structure 50 shown in FIGS. 13-15 is usablewith any of the above-described embodiments of the upper supportstructure 22 to provide the fence 10 with support means which permitseach fence member 20 to be adjustably positioned and releasably retainedin a selected position with respect to the fence rails 16 and 18. If theinfinitely variable support structure shown in FIG. 37 is used the lowersupport structure would be simplified as shown in FIG. 38.

[0064] If the upper support structure 22 shown in FIGS. 3 and 4 is used,the locking member 27 is rotated downwardly away from the upper fencerail 16. This will permit the fence member 20 to be raised and rotatedwith respect to the rail 16 and the lower rail 18 to the selectedorientation. The member 20 rotates on the pin 52 until the member 20 isin the desired position, and the corresponding detent 56 is in placewithin the locking aperture 58A-E on the bottom rail 18. The lockingmember 27 then can be advanced on the thread 26B against the top rail 16to limit the upward movement of the member 20 and lock the fence member20 in the selected location.

[0065] If the embodiment for the upper support structure comprises thespring plunger 34 shown in FIGS. 5 through 9, or the collapsibletensioning insert 42 shown in FIGS. 10 through 12, the adjustment of theassociated fence member 20 is accomplished by gripping the tab 30 on thefence member 20 and applying a moving force. This force will act againstthe bias of the spring loaded plunger 34 shown in FIG. 8, or against thecollapsible tensioning member 42 shown in FIGS. 10-12 to permit thefence member 20 to be rotated into a selected position. Once the member20 is in the desired position, release of the tab 30 will permit thebias of the plunger 34 or the collapsible tensioning member 42 to applya biasing force to the fence member 20.

[0066] The lower support structure 50 on each fence member 20 operatesin essentially the same manner as described above for each embodiment ofthe upward support structure. In each embodiment, the force of gravityand the weight of the fence member 20, assisted in some embodiments by adownward biasing force, will cause the detents 56 to be captured by thecorresponding compatibly configured recesses 60A-E in the indexing andlocking aperture 58A-E. The engagement between the detents 56 and thecorresponding apertures 60A-E will releasably lock the associated member20 in place. If the fence member 20 is to be adjusted further, theupward lifting force on the member 20 will disengage the detents 56 fromthe associated recesses 60A-E of the apertures 58A-E in the lower rail18. The fence member 20 can then be rotated into a desired position andreleased. Gravity, assisted by a biasing force, will re-engage thedetents 56 with the appropriate recesses 60A-E in the lower rail 18 toonce again releasably lock the fence member 20 in a desired location.

[0067] The fence members 20 including the support structures describedabove therefore can be adjusted to change the function, use orappearance of the fence 10. If maximum security or privacy and minimumvisibility through the fence are required, each of the fence members 20can be positioned to be essentially parallel with the upper and lowerfence rails 16 and 18. In the embodiment shown in FIGS. 10-12, the uppersupport structure including the collapsible tensioning member 42 willclose the space between the upper portion of the member 20 and the upperrail 16 to further reduce the visibility through by the fence 10.Alternatively, each fence member 20 can be individually or collectivelyadjusted into any selected position with respect to the fence rails. Forexample, if a position of 60 degrees for the fence members 20 would bedesired to respond to the effect of the sunlight or wind, provideprivacy or perform other uses, one or all of the individual fencemembers 20 can be adjusted to that selected angle as described above andlocked into place.

[0068] FIGS. 16-18 illustrate another aspect of the present inventionwhich allows the components of the fence 10 such as the posts, rails orpickets or fence members to be varied in appearance or changed infunction in a different manner. In this embodiment, each fence member 20is provided on one or more of its faces with adhering or grippingelements. In the illustrated embodiment the gripping elements comprise apair of channels 70, as clearly shown in FIGS. 16 and 17. These channels70 are preferably formed in place when the member 20 is manufacturedfrom a plastic material such as PVC. In FIGS. 16 and 17, each channel 70is positioned along the edge of a face of the member 20 and forms agroove 72 along each edge. The gripping elements may also comprisegrooves formed within the sides of the fence members 20. As shown inFIG. 17, a separate member such as a panel member 74 can be insertedinto the grooves 72. The panel 74 will be removably held in place alongeach side of the fence member 20 by the channels 70. A suitable detentcan be provided to prevent the panel 74 from sliding out of the channels70.

[0069] The panel 74 is selected to have a color, texture or shapedifferent from the color or texture of the associated fence member 20.If the fence member 20 is formed from a plastic material such as PVC,the usual color for the fence member is a light or white color. Thechangeable panel member 74 can be made from a material such as vinylsheeting, and selected to change the color or texture of the member 20.The panel 74 also provides additional protection for the fence member 20such as protection from ultraviolet rays.

[0070] Vinyl sheeting, such as used in vinyl siding for homes, is veryuseful for forming the separate panel members 74. Vinyl sheeting isreadily available in a variety of colors and textures, and can beeconomically formed or sized to be positioned on outdoor structures ofdifferent dimensions. The use of vinyl sheeting to change the appearanceor texture of an outdoor structure in accordance with this inventionresults in substantial economic and manufacturing benefits. The need tomanufacture and inventory a substantial number of structures orcomponents of varying colors and textures is reduced. Instead, the basiccomponents of a structure such as a fence can be modified by providing asupply of readily available and economically manufactured vinyl sheetsof different colors or textures.

[0071]FIG. 18 shows a fence system similar to the system shown in FIG. 1but modified to include inserts 75A-75F on the faces of the fencemembers 20. For illustrative purposes, each insert 75A-75F is shown inFIG. 18 as having a different color, e.g., green, yellow, blue, orange,brown and silver, respectively. The fence panels could also comprisesolar panels 90, as shown in FIG. 21, or panels having a selectedtexture. As noted above, these changeable panels can be selected for avariety of purposes, such as to change a portion of a fence to match thecolor of a nearby house, to reflect holidays or changes in seasons forproviding the fence with decorative patterns, to display messages, tocollect solar energy, or for other uses.

[0072]FIGS. 19 through 21 illustrate further embodiments of the systemfor changing the appearance or function of the fence 10 in accordancewith this invention. In FIG. 19, a generally u-shaped channel member 80is designed to be retrofitted onto an existing fence member 20. Thechannel member 80 can be adhered to the face of the member 20 by asuitable adhesive, or held in place by other forms of fasteners. Thechannel member 80 defines a channel 82 at each edge of the member 20which creates grooves 84.

[0073]FIG. 20 illustrates the fence member 20 in FIG. 19 having achannel member 80 joined to its face and further having an insert member89 positioned in place in the grooves 84. This channel member 80 and/orthe insert member 89 can have a different color, texture or shape ascompared to the appearance and material forming the fence member 20.Each fence member 20 including the channel member 80 can be changed byselecting the inserts 89 to suit the particular use or appearancedesired for the fence member. Other inserts such as the panels 74 or thesolar panel 90 shown in FIG. 21 can be inserted within the channelmember 80.

[0074]FIG. 21 illustrates a further aspect of the present inventionwhere the structure inserted onto the face of the fence member 20comprises a solar energizing element or laminate such as a solar panel90. In this embodiment each of the fence members 20 that carry a solarpanel 90 will be capable of collecting solar energy from the sunlight.The above-described upper and lower adjustable supports for each fencemember 20 can be used to position the fence members 20 to maximize theeffectiveness of the solar panels 90 in response to the changes inseasons, or to accommodate other changes in environmental conditions.Suitable conducting wires or fittings and connectors can be included inthe structure to distribute the energy collected by the solar panels 90.For example, electrical wires 91 can be connected to the solar panel 90and extended through suitable holes in the fence member 20. The wires 91can be connected to other wires, fittings or connectors in the fencesystem

[0075] The embodiments of the invention shown in FIGS. 16-21 can be usedto change the appearance of the fence member 20 for a variety ofpurposes. As an example, the structure can be used to change a normallywhite fence to a darker color that matches or complements the color ofthe associated house or other structure. The fence member 20 can bechanged in appearance to reflect the seasons or holidays or other eventsimportant to the user. Alternatively the panels 74 can added to thefence member 20 to carry a message such as an advertisement. Otherfunctions, such as the collection of solar energy by the solar panels90, can be added to the fence.

[0076] The embodiments of the invention illustrated in FIGS. 16 through21 can also be used in other outdoor structures such as railings or deckmembers or the like to change the appearance, color, texture or functionof the structure.
